Further, please refer to FIG. 6B, which is a schematic structural view of a bulb of another example of the present invention. The main difference between FIG. 6B and FIG. 6A is that the pattern light sources 671, 672 having image patterns are directly disposed on the turntable 611 in FIG. 6B. The user can rotate the turntable 611 via the rotating member 620 on the bulb 601 to switch the projected image pattern. Because the turntable 611 has a plurality of pattern light sources (such as 671, 672) with different image patterns, when the turntable 611 rotates, the pattern light sources 671, 672 thereon will rotate along with the touch circuit shown in FIG. 130 and drive circuit 120 are used to activate different pattern sources 671, 672 to present different patterns.

After the above description, those skilled in the art can easily infer the implementation thereof, and will not be described here. 9/17 201213710 Please refer to Fig. 7' which is another way of projecting an image pattern according to the present invention. The embodiment is formed by stacking a plurality of light guide plates 710 740 740 having gaps therebetween. The pattern light sources 761 764 764 are respectively disposed on the sides of the light guide plates 710 740 740 to drive light into the light guide plate 71 . 〇~74〇<) Each of the light guide plates 710 to 740 has a different image pattern. When one of the pattern light sources 761 to 764 emits light, the light is incident on the side of the corresponding light guide plates 71 〇 740, and then the corresponding image pattern is projected on the light permeable cover 194. When only the pattern light source 761 on the side of the light guide plate 710 is illuminated to emit light, since there is a gap between the light guide plates 710 to 740, the light may be on the bottom surface of the light guide plate 710 due to the existence of the two gaps in the light guide plate 71. The total reflection is performed without entering the light guide plate 720 until the light image is penetrated by the image pattern on the light guide plate 71, so that only the pattern of the light guide plate 710 is present; when only the pattern light source 762 on the side of the light guide plate 72 is When the light is illuminated and the light is emitted, the light is also totally reflected in the light guide plate 720 due to the existence of the gap in the light guide plate 72, until the light encounters the image pattern on the light guide plate 72 to penetrate the light guide plate, and guides The light plate 71Q presents only the image pattern on the light guide plate 720. Therefore, the image patterns on the light guide plates 71A to 74() do not interfere with each other. In addition, according to FIG. 1, the luminaire 100 has a mechanical dimming function, and the light permeable cover 194 is rotatably coupled to the housing 196.

The driving circuit 120 adjusts the brightness of the illumination source 15 according to the rotational position of the light-transmitting lamp 194: when the light-transmissive fresh 194 starts to rotate from the starting position, the drive-channel 12 turns to two..., the moon light source 150, and then The rotational position of the light transmissive cover ι 94 adjusts the brightness of the illumination source 150. When the translucent cover 194 is rotated to a lower limit position, the drive circuit 120 turns off the illumination source 150. . At the same time, reference is made to Fig. 8' as a schematic structural view of a 10/17 201213710 bulb 800 having a dimming device 14A and a dimming mechanism 192. The dimming device 14 is coupled to the dimming mechanism i92 and the driving circuit 120, and the dimming mechanism 192 is coupled to the translucent cover 194. The dimming device 140 and the dimming mechanism 192 can generate a 5-week number along the rotational position of the translucent cover 194, and the driving circuit 120 adjusts the brightness of the bulb according to the adjustment signal. The dimming device 140 has a variable electric 卩 and 891 The variable resistor 891 is disposed on the printed circuit 892. The dimming device HO converts the resistance value of the variable resistor 891 into a voltage signal or a current signal to the driving circuit 120, so that the driving circuit 120 adjusts the light bulb 800. The brightness of the illumination source. The dimming mechanism 192 mainly includes a lens gear 881 and a transmission gear 882 and a transmission shaft 883, wherein the lens gear 881 is disposed in the housing 196 and connected to the lower edge of the transparent lamp cover 194. The transmission gear 882 is disposed at The housing 196 is coupled to the lens gear 881. The transmission shaft 8 is connected to the transmission gear 882 and the variable resistor 891 to adjust the variable resistor 89. The lens gear 881 has an arc shape, for example, along with the transparent lamp cover. 194 rotates to drive the transmission gear 882 to rotate. The resistance of the variable resistor 891 can be adjusted through the rotation of the transmission shaft 883 'the transmission gear 882. Further, the dimming mechanism is made to avoid excessive rotation of the user. 192 and the dimming device • I40 is damaged, and two stop portions (not shown) may be disposed at both ends of the lens gear 881 for limiting the rotation angle of the lens gear 881. When the lens gear 881 is rotated to the stop portion (ie, the aforementioned bottom position) is stopped. Alternatively, an arc-shaped guide rail (not shown) is disposed in the housing 196, and the light-transmitting cover 194 is designed with a sliding portion (not shown) along which The arc-shaped guide slides, and stops when the sliding portion of the transparent cover 194 touches the end of the arc-shaped guide (that is, the aforementioned limit position). The drive circuit 120 adjusts according to the resistance value of the variable resistor 891. The illumination source 15 〇 is free. That is to say, by the dimming device 140 and the dimming mechanism 192, the user can adjust the brightness of the action bulb 1 by rotating the transparent cover 194. It is worth noting that The optical device 140 and the dimming mechanism 192 are not limited to those shown in FIG. 8. For example, 11/17 201213710, the furnace is turned off: (10) the medium-sized variable resistor 891 can be realized by using an anti-discharge, and the dimmer is used to realize the elastic piece by using the elastic piece. As the light-transmitting lamp cover 194 rotates, it contacts the different pins of the hybrid _ the entire ancestors.
